- a set of such a sleeve and a ceramic roller and a Ver drive for mounting such a sleeve on a ceramic roller will be presented.
- a sleeve for storing a ceramic roll in a rolling stove has a receptacle for one end of the ceramic roller, the receptacle being surrounded by a jacket wall, the jacket wall having a waist section in the axial direction and a clamping section located therein having, wherein a wall thickness of the jacket wall in the waist section is smaller than in the vicinity of the waist section, and wherein a cross-sectional area of the receptacle in the clamping section is smaller than in the vicinity of the Klemmab section.
- the sleeve is designed and equipped to store a ceramic roll in a rolling oven.
- the ceramic roller is preferably one of many ceramic rollers which are arranged in the roller hearth furnace and are intended for the transport of components through the roller hearth furnace.
- components especially those made of steel, can be thermally treated, for example for press hardening.
- the roller hearth furnace is preferably designed for the thermal treatment of components, in particular for motor vehicles.

- the sleeve gives the ceramic roller a connection via which the ceramic roller can be connected to the drive and bearing device.
- the waist section and the clamping section two axial sections of the shell wall are defined: the waist section and the clamping section.
- the clamping portion lies within the waist portion. This means that the clamping section does not protrude beyond the waist section either on one side or on both sides and also does not coincide with the waist section.
- the jacket wall preferably has further axial sections. It is particularly preferred that the waist section is spaced from the end faces of the receptacle. is arranged.
- the waist portion and the pinch portion are defined by the conditions described below.
- different sections can be identified as waist sections and / or that different sections can be identified as clamping sections. It is sufficient that a section can be identified as a waist section and that a section can be identified as a clamping section - alternatively possible assignments of the sections are not important.
- the waist section is defined in that in this the wall thickness of the man telwand is smaller than in the vicinity of the waist section. This means that the wall thickness of the jacket wall in the waist section is reduced. Even if this is preferred, the wall thickness of the jacket wall in the waist section does not have to be constant. Outside the waist section, too, it is preferred, but not necessary, for the wall thickness of the jacket wall to be constant. In both statements, the term “constant” refers to the fact that the wall thickness remains unchanged when viewed along the axial direction.
- the waist section is defined axially, the "surroundings of the waist section” are to be understood as meaning the sections of the jacket wall that axially adjoin the waist section.
- the wall thickness of the jacket wall does not have to be constant the "area around the tail lenabitess", the wall thickness of the jacket wall at the edges of the waist section is decisive. These edges are not considered part of the waist section.
- the wall thickness is preferably constant, which applies in particular to the entire jacket wall. If the wall thickness should vary in the circumferential direction, every axial section of the jacket wall comes into consideration as a waist section, for which the condition is met over at least part of the circumference of the jacket wall that the wall thickness of the jacket wall in this section is smaller than in the Environment of this section. Preferably, in the waist section over the entire circumference of the jacket wall, the condition is met that the wall thickness of the jacket wall is smaller in the waist section than in the surrounding area of the waist section. Since an axial section is considered, the “area surrounding this section” is also defined in the axial direction. Therefore, only the area surrounding the section at the respective location in the circumferential direction is relevant.
- the wall thickness of the jacket wall is preferably in the range from 0.5 to 1.0 mm. In the vicinity of the waist section, the wall thickness of the jacket wall is preferably in the range from 1 to 2 mm.
- the clamping section is defined in that the cross-sectional area of the receptacle is smaller in it than in the vicinity of the clamping section.
- the cross-sectional area of the recording indicates the area of the two-dimensional extent of the recording when viewed perpendicular to the axis of the recording.
- the recording is the space that is surrounded by the jacket wall.
- the cross-sectional area of the receptacle, when viewed perpendicular to the axis of the jacket wall, is the area that is delimited by the inside of the jacket wall.
- the cross-sectional area of the receptacle in the Klemmab does not have to be constant. Outside the clamping section it is also preferred, but not necessary, for the cross-sectional area of the receptacle to be constant. In both statements, the term “constant” refers to the fact that the cross-sectional area remains unchanged when viewed along the axial direction.
- the "surroundings of the clamping section” are to be understood as the sections of the jacket wall which axially adjoin the clamping section.
- the cross-sectional area of the receptacle does not have to be constant the “environment of the clamping section” is determined by the cross-sectional area of the receptacle at the edges of the clamping section. These edges are not considered part of the Klemmab section.
- the diameter of the receptacle in the clamping section is smaller than in the vicinity of the clamping section.
- the term diameter - which, according to the mathematical definition, refers to a circular cross section - is not used for such a deformed receptacle. Instead, consider the distance between the inside of the shell wall and the axis of the one telwand. In the case of a cylindrical receptacle, this distance corresponds to its radius.
- the cross-sectional area of the receptacle in the clamping section is smaller than in the vicinity of the clamping section can in particular be achieved in that the distance between the inside of the jacket wall and the axis of the jacket wall in the clamping section is smaller than in the vicinity of the clamping section.
- the distance between the inside of the telwand and the axis of the shell wall does not have to be constant.
- the one telwand can deviate from a rotationally symmetrical shape. If the distance of the inside of the jacket wall from the axis of the jacket wall varies in the circumferential direction, any axial section of the jacket wall for which the distance of the inside of the jacket wall from the axis of the jacket wall is smaller than in the vicinity of this section comes into consideration as a clamping section.
- the means refers to a level perpendicular to the axis of the shell wall.
- the condition is preferably fulfilled in the clamping section over the entire circumference of the jacket wall that the distance between the inside of the jacket wall and the axis of the jacket wall is smaller in the clamping section than in the vicinity of the clamping section. Since an axial section is considered, the “surroundings of this section” is also defined in the axial direction. Therefore, only the surroundings of the section at the respective point in the circumferential direction are decisive.
- the distance between the inside of the jacket wall and the axis of the jacket wall in the vicinity of the clamping section is preferably in the range from 24 to 100 mm.
- the distance of the inside of the shell wall from the axis of the telwand Man in the clamping portion is 0.15 to 1.00 mm smaller than in the vicinity of the clamping portion.
- a comparatively very small deformation of the shell wall is therefore sufficient.
- this cross-sectional area is elastically expanded so that the minimum distance between the inside of the jacket wall and the axis of the jacket wall in the clamping section corresponds to the resulting cross-sectional area of the ceramic roller.
- the resulting radial force between the ceramic roller and the sleeve is so high that a drive torque can be positively transmitted to the ceramic roller via the sleeve. It is preferred here that the radial force is not higher than the value to be endured by the ceramic roller.
- the radial force due to the described design of the sleeve is sufficiently high for a non-positive connection between the sleeve and the ceramic roller, even at high temperatures and despite the oversize reduced by the different temperature expansion coefficients of the sleeve and the ceramic roller.
- the elasticity of the clamping section is preferably designed in such a way that there is no permanent, ie plastic, deformation of the clamping section in any operating state.
- the jacket wall is preferably closed in the circumferential direction. This applies to at least one axial section, in particular at least for the waist section and / or for the clamping section. Particularly preferably, the jacket wall is completely closed dig. Openings on the front sides are not openings in the jacket wall. In particular, the jacket wall does not have any axial slots.
- Such a configuration could be provided in order to compensate for the different expansion of the ceramic roller and the sleeve via a spring effect that can be achieved therewith. Since the rigidity of the sleeve is very limited in this construction, a required preload can only be maintained in a very limited area in this construction. Due to the design, in particular with the waist section and the clamping section, such slots are not required. As a result, the slots can be dispensed with and the stability of the sleeve and the connection to the ceramic roller can be increased. In addition, the production is simple, because no slots have to be generated and in this respect a manufacturing step is omitted.
- the wall thickness of the jacket wall in the waist section is 20 to 60% of the wall thickness of the jacket wall in the vicinity of the waist section.
- the cross-sectional area of the receptacle in the clamping section is 0.03 to 0.3% smaller than in the vicinity of the clamping section.
- Expansion of the clamping portion at least 70% of an axial expansion of the waist portion.
- the axial extension of the clamping section is between 70% and 90% of an axial extension of the waist section.

- the set preferably comprises two sleeves. In that case, one of the sleeves can be pressed onto each end of the ceramic roller.
- the cross-sectional area of the receptacle is smaller in the clamping section than in the vicinity of the clamping section, as the cross-sectional area of the receptacle is smaller than the cross-sectional area of the end of the ceramic roller only in the clamping section.
- the cross-sectional area of the end of the ceramic roller is the area that covers the outside of the ceramic roller when viewed perpendicular to the axis of the ceramic roller at the end of the ceramic roller.
- the end of the ceramic roller is the part of the ceramic roller that is received by the sleeve. If the cross-sectional area of the ceramic roll should not be constant at its end, an average is decisive.
- the cross-sectional area of the receptacle is therefore equal to or greater than the cross-sectional area of the end of the ceramic roller. If the sleeve is pressed onto the ceramic roller, the sleeve is held on the ceramic roller in particular via the clamping section. This is a clamp connection, which is what the name clamp section is based on.
